ABSTRACT:
Pulp degassification is effected by a structure that may be mounted on a pulp treatment vessel, such as an oxygen reactor blow tank. The degassifier includes a housing that is substantially circular in cross-section and tapers from a first end to a second end along a central axis. A pulp inlet is adjacent the first end and introduces pulp tangentially and an outlet is adjacent the second end extending concentrically with the central axis. A blade assembly is mounted for rotation about an axis generally coincident with the housing central axis, and the blade assembly is rotated to impart a high speed rotational velocity component to the pulp as it enters the housing. A gas outlet is adjacent the housing first end, vertically above the housing second end, and adjacent the central axis. A conically shaped baffle or the like is provided surrounding the gas outlet to prevent short-circuiting of pulp from the inlet to the gas outlet.
